Misconceptions about waterproof membrane elongation
There is a wide misconception regarding the elongation properties of waterproof membranes and their ability to bridge cracks that form post membrane application.This bulletin endeavours to clarify the real meaning of elongation and elasticity in relation to bridging properties.
Green walls and the question of fire compliance
With the increasing use of vertical green walls for sustainability and well-being, questions about their fire performance and compliance with the building code have been raised. Green wall construction is captured in either one of two places in the building code and it is dependent on where the green wall is located, with the typical path to compliance achieved using a performance-based approach.
Using hydrogel to replace membranes in basement waterproofing
A hydrogel formation can be induced in concrete by means of catalytic water-borne colloidal silicates. The hydrogel completely seals the porosity of the concrete, immobilising the moisture and preventing watermovement into or through the slab.
Prescriptive vs. performance specifying: a trade-off between design liability and project risk
n this highly litigious modern-day society that we live, arse-covering has turned into an art form. Liability is like a hot potato and it’s all about transferring it away from oneself and onto another party.In engineering and architectural design that other party is usually the contractor. The designer is in a great position to pass the buck down the line wherever possible.
