Challenge

The new grandstand at Epsom Racecourse was designed and built out of precast concrete and as such had a significant amount of construction joints that needed to be waterproofed.

Although the precast sections did have a primary form of protection, it was essential that no water leaked through the precast sections into a new food hall court constructed beneath the grandstand.

Advanced Basements Ltd, an approvedNewton Specialist Basement Contractor, was contacted by the architect to design and install a concrete joint waterproofing solution.

Solution

Advanced Basements installed Newton 503 Cavity Drain membrane across the joints to form a catchment tray system to divert any water that could potentially permeate down to underneath the bottom of the seating of the grandstand.

Newton 902 primer was applied to a 300mm band either side of the construction joints so as to create a chemical bond for the Newton Overtape to seal the edges of the membrane section.

The 503 membrane was installed in a 400mm band across every construction joint, sealed to the primer with the Overtape then a mechanical strap was fixed through all elements to hold the products into position.

Outcome

The solution was quick and easy to install and prevented the need to inject resins or grouts into the joints, making considerable cost savings.

There was only minimal surface preparation required before installation and as the cavity drain membrane was detailed across the joints there was no need to install membranes across the entire underside of the sloping soffits.
