AQUELLUX S PROTECTS HINUERA STONE

An in-house experiment conducted using Hinuera Stone samples clearly shows how effective AQUELLUX S silane/siloxane water repellent is for treating Hinuera Stone surfaces. A sample of stone was treated with AQUELLUX S and submerged in water along with an untreated sample. After immersion in water for 4 months, the AQUELLUX S treated block increased in weight (due to water absorption) by 5% whereas the untreated block increased by 28% - almost 6 times more water was absorbed. Furthermore, the treated block remained essentially unchanged visually underwater even after an extended period of submersion totaling 6 months.

Due to the degradation of the stone by weathering, the loss of thermal properties due to water absorption and the unsightly colour change of the stone when wet, AQUELLUX S is a cost-effective method of providing water repellency without changing the appearance of the stone when dry. It also maintains the dry-state appearance of the stone during wet weather.

The photos below show the treated block of Hinuera Stone as removed from the water after 6 months immersion and the same untreated block after 6 months immersion. It must be noted that the untreated block was green and slimy when removed from the water, whereas the AQUELLUX S treated block was more or less the same colour as a new, dry piece of Hinuera Stone. Furthermore, when removed from the water, the AQUELLUX S stone was dry whereas the untreated stone was still thoroughly wet even after 24 hours of drying at 15 degrees Celsius ambient temperature.

The AQUELLUX S treated sample is on the left side of the photos, the untreated sample is on the right side shown immediately after being removed from the water after 6 months submersion. A plain block of Hinuera Stone is behind the samples on the first photo, and on the second and third photos, the samples are placed on top of this block of stone. The third photo shows the result of pouring water on both samples - the AQUELLUX S treated sample repels the water away, whereas the untreated block immediately absorbs the water changing colour.

KRYSTOL CONCRETE WATERPROOFING SYSTEM

Te Wharewaka O Poneke Building –Wellington, New Zealand

The Te Wharewaka O Poneke Building (Canoe House) was developed to serve as the entertainment centre for the 2011 Rugby World Cup. The development showcases the rich history of Maori art and culture, and includes exhibition and function areas, a café and offices. It will also host powhiri (a Maori ritual ceremony), carvings, cultural performances and interactive historic displays.

The site was developed on reclaimed land along the waterfront in central Wellington, making waterproofing essential.

The project team selected the Kryton Waterproofing System to ensure the building and valuable Maori art would be protected from water and last the life of the building. The contractor also selected Kryton product to provide extra protection to the concrete used for the marine grade landscaping.

The total project used 1400m³ of concrete, of which 1100kg of KIM was supplied to waterproof in the critical areas. With its location adjacent to the ocean, KIM was the optimal choice for this project where water exposure or ingress is a concern.

The Te Wharewaka O Poneke Building opened in February 2011.

Note the Odlins Building (NZ Stock Exchange) to the right of the second photo. KIM was successfully used to waterproof the below-grade carpark. 

EPAR 124 TLS - Fast-Setting Epoxy Grout System

EPAR 124 TLS is a fast-setting pourable epoxy grout. It is designed to quickly develop strength and provide excellent resistance to creep. EPAR TLS 124 is provided as a two-part system with both the hardener and resin being coloured to ensure proper and complete mixing. EPAR TLS 124 can be used in low temperatures.

For the Thorndon flyover (Wellington Motorway) barrier reinstatement, EPAR TLS 124 was used to secure the barrier bolts into the concrete deck. EPAR TLS 124 was also used on the road section below the bridge to epoxy the street lighting bolts in place. Fulton Hogan, the primary contractor, found EPAR TLS 124 very easy to use and the coloured components helped ensure complete and accurate on-site mixing. For this project, the epoxy grout was supplied in 900ml packs for convenient handling.

AQUELLUX S WB - High-Performance Silane/Siloxane Water-based Water Repellent

Fraser Brown & Stratmore is pleased to announce the development of a new water based silane/siloxane water repellent, AQUELLUX S WB.

AQUELLUX S WB compliments our solvent based water repellent, AQUELLUX S. It is a true silicone water repellent based on silane/siloxane technology. It is not a silicate based material which offer only short-term performance and require reapplication every year or two.

AQUELLUX S WB can be applied to most masonry and concrete substrates, even damp surfaces. It is a stable water based product and does not require remixing or dilution before use.

AQUELLUX S WB:

• Provides good depth of penetration
• Excellent beading effect for surface repellency
• Highly stable on alkaline substrates (concrete and masonry)
• Allows the substrate to breathe
• Superior to silicate based materials (which are primarily recommended for treating clay pavers, etc)
• Non-DG for transport and storage

AQUELLUX S WB can be used internally for feature walls, etc.

AQUELLUX S WB is available now in 4, 20 and 200-litre containers.
