Liquid Membrane Systems
At ASAP Waterproofing we utilise a variety of Liquid membrane systems depending on the job requirements. Our first choice is a Tamsi Liquid membrane System as it provides the benefits of a durable sheet membrane with the unique feature of a multi layer seamless finish, eliminating joints, overlaps and other risk points associated with welding and abutting traditional sheet membrane systems. Tamsi Liquid Membrane system using Tamsi epoxy primer and Tamsi Tough – is suitable for permanent exposure to varying climatic conditions, UV light and foot traffic. We are also experienced in the use of PVC Sheet membrane systems for high risk areas that come with long 15-30 year manufacturers warranties.
PVC Sheet Membrane Systems
ASAP Waterproofing have extensive experience in the selection and application of liquid membranes. We utilise a variety of Liquid membranes that range from a single part liquid rubber membrane designed for waterproofing wet areas, showers, laundries, roofs, terraces, balconies, decks, concrete slabs and general structures that will be covered over with toppings, tile beds or overlay finishes. The membrane when cured is the compatible bonding surface for a variety of toppings, renders, tiles and screeds to adhere without concerns of incompatibility or de-bonding. We also use Gripset RD wich is a flexible elastomeric liquid membrane designed to waterproof a variety of external and exposed surfaces.
Crack Injection
Water leakage often occurs through concrete cracks, concrete construction joints, masonry cracks and blockwork. Polyurethane injection resins have been designed specifically for such applications and range from low viscosity, rapid reacting, rigid leak sealing resins for high water cut off and void filling to flexible and semi-flexible polyurethane leak sealing resins for general water stopping repairs. We also utilise an acrylic leak sealing resins that offer a ultra low viscosity injection resin for hairline concrete cracks and joints, masonry cracks to sealing honeycombed locations in concrete retaining walls and slabs to brick work waterproofing. The products we use incorporate an anti-corrosive agent that actively protects the steel reinforcement from corrosions occuring.
