Remedial waterproofing solution to a damp issue in an annexe
Our client contacted us at Waterstop Solutions for a remedial waterproofing solution to a water ingress problem in the annexe on their property in Brisbane.
Our inspector carried out a site inspection to identify the next step forward, which was to remove a section of the topping slab and the plastic underneath it next to 3 of the 4 walls. This was to enable access to the floor to wall joints in order to perform high-pressure leak sealing injections with hydrophilic polyurethane resin. Once completed, a reverse side waterproofing system was to be installed to the wall/floor junction and turned up the masonry wall after surface preparation.
Our onsite leak sealing specialists, Gemma and Mick, advised that after removing a section of the topping slab, they identified rising damp through the concrete floor slab underneath the topping slab. Additionally, they discovered two concealed joints that run through the concrete floor, which showed signs of moisture ingress.
To treat the rising damp and the joints in the floor, the topping slab covering the concrete floor needed to be removed. The joints in the floor were treated with high-pressure leak sealing injections, creating a three-dimensional waterproof seal in the building element. (The same process as performed to the floor to wall joints).
The walls and floor surfaces were ground smooth and vacuumed before joint sealant and the reverse side water-borne epoxy (WBE) waterproofing system were installed.
Because the WBE moisture barrier is susceptible to damage from UV-light and abrasive damage caused by foot traffic and objects (such as furniture) being dragged across its surface, we recommend installing a flooring system (i.e. tiles or carpet) to protect the moisture barrier.
