Christchurch Hospital Acute Services Building

23 Aug 2021 by Equus Industries

The Christchurch Hospital Acute Services Building, opened in 2019, was a $483 million anchor project outlined by the Christchurch Central Recovery Plan. The Building houses operating theatres, an intensive care unit, state of the art radiology department, acute medical assessment, an expanded emergency department and a rooftop helipad. The building was a 62,000 sqm project designed by Katoa Health Design with main building contractors being CPB Contractors.

Equus Industries is pleased to have been involved in a number of elements of this project including DuO and Duotherm membrane roofs, balconies, plant decks, Keim Granital Coatings on the building’s exterior, DeboFlex tanking membrane to the underground construction, and Aquafin 2KM for waterproofing the water tanks.

DuO and Duotherm Roofing

Equus Soprema (formerly De Boer) DuO Two Layer membrane system was installed to the Level 2, 3, and 9 roofs and external plant decks of the Acute Services Building. The Duo Two Layer system consisted of a DuO GW (Grey White) Capsheet and DuO Basesheet welded to concrete, plywood and roof board substrates. The Duotherm Warm Roof system included the DuO Two Layer Membrane System with a mechanically fastened base sheet installed over Kingspan Thermal insulation board. The system also includes a vapour barrier that was specifically chosen for the vapour distribution of the building.

These systems were chosen for this project because the membrane provides a hard, stable, UV-resistant, and flexible waterproofing system for the building with a guaranteed R value of R3.5. This provides the precinct with guaranteed condensation control for a healthier building, and energy cost savings when it comes to heating and cooling.

Duotherm Balcony with Pavers

Equus Soprema (formerly De Boer) Duotherm warm roof system was installed on the level 3 outdoor courtyard area with pedestals and concrete pavers installed over top. The system consisted of a DuO GW Capsheet and DuO basesheet torched over a Unifix Permabase Dek roof board, Kingspan thermal insulation board and vapour barrier over a concrete substrate. The Permabase Dek roof board provides excellent compressive strength to increase the roof durability for foot traffic.

Keim Granital Exterior Coatings

Keim Granital is a sustainable, water-borne, liquid mineral silicate coating and was applied to the exterior concrete panels. The durability of the coating provides the building with a colourfast and water repelling protective finish while the natural properties ensure a breathable, long life, low maintenance finish.


Equus Soprema DeboFlex 3.5 Special (formerly De Boer Debobase) tanking membrane is a high-quality waterproofing membrane designed to be torched, or loose laid for underground waterproofing. DeboFlex Tanking was applied to the underground construction of the building to produce a strong, puncture resistant layer that bonds to the concrete.

Aquafin 2K/M Plus Water Tank

The lower ground fire water tank for the building required interior waterproofing across the walls and floor of the tank. Aquafin 2K/M Plus cementitious waterproofing is a two-component waterproofing system that provides a seamless, crack bridging membrane with flexibility and excellent adhesion to concrete. This cementitious system was applied to the concrete walls, and concrete slab of the water tank room forming a watertight barrier of interior waterproofing.

Chevaline Dexx Plant Rooms

The Chevaline Dexx liquid applied, reinforced membrane is a floor coating formulated for high adhesion and water resistance to create a flexible, durable waterproofing membrane. This system was used on the level 2 and level 9 plant room floors with a Traxx 2000 topcoat in the walkways to ensure durability in the walkway areas.

Equus Industries
New Zealand
Equus Industries Limited is a private limited liability Company (#120201) incorporated in Blenheim New Zealand in 1982.  The Company commenced business, immediately after formation, as a manufacturer of specialist coating systems for commercial buildings. This remains the main thrust of the operation to this day, with additional high quality complementary products introduced to extend the range to encompass a full range of coating and waterproofing materials for all types of construction.The Company has been an exporter of specialist lines from late 1983 to date. The Company has exported regularly to Australia, the South Pacific and South East Asia, and presently has strong links with distributors in Australia and South East Asia.Since formation, growth has been steady and continuous at an average 15% annual compound rate. The Company now has a multi-million dollar turnover and is respected as a supplier of quality protection materials to the construction industry.PRODUCT RANGEEquus Industries markets a wide range of high build waterproof finishes, textured coatings, and protective coatings under the brand names Chevaline, Traxx, Protexx, Thermexx and Equus. Our expertise is particularly in the areas of high build acrylic coatings and membranes, waterborne epoxies and high solids one – and two component urethane coatings. The Company is most probably the leading Australasian manufacturer in the area of liquid-applied acrylic roofing membranes, and single-component moisture-cure urethane coatings. The Company has established very close relationships with its principal raw material suppliers in these fields, and operates in the forefront of technology in these areas.Our prime object has been to place the Company in the position of being able to supply all finishes and waterproofing materials required to protect buildings from sub-basement to roof levels. Where the technology or manufacturing requirements are outside of our standard capabilities, the Company has secured distribution arrangements for appropriate products from leading manufacturers in their respective fields as noted under `Agencies’ later in this profile.Where appropriate, materials are covered under a Warranty system which is operated in conjunction with the Certified Applicator from the Equus Network who carries out the work on any particular project.All products are manufactured under strict Quality Assurance standards monitored and controlled by our in-house laboratory. The Company has a TQM philosophy and is at present working within the parameters of an ISO9002 framework.FACILITIESThe Company’s production facility, laboratory and Head Office are located on 1.2 hectares of land in the Riverlands Industrial Estate, Blenheim, New Zealand.The production equipment is modern and standardised, and the Plant has a capacity of up to 1.2 million litres of product per annum when operated on a single-shift basis. There is considerable room for expansion of the facility to cope with all requirements in the foreseeable future.Additionally, the Company operates stores in Auckland, Wellington, and Christchurch, where basic stocks of commonly used products are held for immediate supply. The Company regards itself as a custom-formulator, rather than a manufacturer of conventional products, and stock holdings of standard products are rationalised for maximum stock turnover.Technical representatives service both Clients and Certified Applicators, working from offices associated with the stores in all areas. Full technical back up to the sales staff is provided from the Head Office/Laboratory facility in Blenheim.DISTRIBUTION NETWORKEquus Industries Limited is not directly involved in retail sales. Distribution of Equus products is normally to Certified Applicators who are familiar with and trained in the use of the Equus range of products either in part, as Specialist Applicators for product ranges within the Network, or in total for major Applicators and those working in smaller centres.A close relationship between Equus Certified Applicators and Equus Industries ensures that there is full co-operation on site between the Manufacturer’s Supervisory/Technical Staff, and the Applicator’s own staff. Quality Assurance Programmes instituted by the Manufacturer are therefore meaningful, noting that programmes are generally written for individual contracts to take in all aspects of work on that particular contract. This facet of the operation is controlled by the Company Compliance Manager.DIRECTORATEThe Company was founded, and has been operated since inception, by the current Directors, who are:Brian J Greenall BE (Chem), MNZIC, FTSC, AMIChemEManaging DirectorMarinus Wagenvoort BSc, MNZIC, ATSCTechnical DirectorAnd were joined in 2006 by:Rob Roxburgh – General Manager / DirectorNikki Brown – Financial and Administration DirectorThese Directors have all been associated with the Company for a number of years including time in Senior Management roles and bring youth, skills and vitality to ensure the continued strength of the organisation into the future.It should be noted that the Directors and senior technical representatives have amongst them over 170 years combined experience in the surface coatings and construction industries.ASSOCIATED PARTNER COMPANIESAs mentioned previously, Equus Industries Limited has formed a firm association with a number of companies outside New Zealand to ensure that the best possible products to fulfil market requirements, and to meet our objective of ensuring that we have available all protective materials required on a project, which can then be sourced from one supplier, generally through one Approved Applicator.These companies include:De Boer N.V – BelgiumUnique quality torch-on roofing and tanking membranes and ancillary products.Schomburg GMBH & Co KG – GermanyCementitious waterproofing, adhesives and ancillary products.Kingspan Insulation Ltd – UKPolyisocyanurate foam building insulation products.Recticel Insulation – BelgiumPolyisocyanurate foam building insulation products.RPM – Belgium/Alteco – Belgium/GermanyMMA and PUMMA flooring and waterproofing systems.Danosa – SpainAPP torch-on membranes, self-adhesives, sound insulation and associated materials.Keimfarben GMBH & CO KG – GermanySilicate paints and plasters.Sealboss Concrete Solutions – USAPolyurethane and epoxy injection systems.In all cases, Equus Industries Limited has the distribution rights for the New Zealand Market.
