EPAR CRACK INJECTION

EPAR CRACK INJECTION epoxy (aka EPAR 226 LV CI) is a low viscosity, unfilled solvent-free epoxy with excellent mechanical properties. EPAR 226LV CI is used as a crack injection epoxy for concrete repairs. The mixed viscosity is typically 375 – 470 centipoise (cps) at 20oC. EPAR CRACK INJECTION epoxy has a 1 to 3 (Hardener to Resin) mix ratio.

CONCRETE BLOCK SEALER SYSTEM

We are pleased to introduce our porous masonry sealer, CONCRETE BLOCK SEALER. CONCRETE BLOCK SEALER is a clear high solids, low VOC waterborne sealer, which when used as part of a complete system including AQUELLUX S WB, is effective in completely sealing porous masonry such as concrete blocks, and acts by blocking the pores against water ingress while not changing the appearance of the substrate to any significant extent. The CONCRETE BLOCK SEALER SYSTEM meets the requirements of CCANZ CP 01:2014 Code of Practice for Weathertight Concrete and Concrete Masonry Construction, section 4.4 Clear Coating System when applied as directed (compliance requires application by way of an approved applicator).

EXTENDED POT LIFE HARDENERS

A liquid epoxy system has a defined pot life which is generally defined as the time after mixing the hardener and resin together thoroughly that the epoxy can be used or applied. During warmer weather (and when larger amounts are mixed), the pot life is reduced and this can make application of the epoxy within its pot life more difficult when larger areas are to be coated. FB&S has introduced an Extended Pot Life version of the hardeners used for EPAR 226, EPAR 733HV and EPAR S liquid epoxy systems to help increase the usable pot life when applying these epoxies. Please contact us for details.

STRIPCRETE

FB&S introduces our new Concrete StripCrete. StripCrete is safe biodegradable solution designed to soften and easily remove concrete or cement residues from tools or concrete placing equipment. It eliminates the need for hammering, sand blasting or hazardous strong acids to remove old concrete residues. StripCrete does not contain hydrochloric acid. StripCrete works by "softening" the layer of old concrete which then allows easy removal.

FAST SETTING REPAIR MORTAR

FB&S has developed a fast setting cementitous repair mortar specially formulated to undertake structural repairs and restoration work. This product can be used where a fast setting (3 minutes) cementitous material is required for a wide range of concrete repairs.

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 totalling 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.

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 where water stains may be an issue.

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