Remedial Waterproofing
Remedial waterproofing solutions designed to address water ingress, failed membranes and underlying substrate defects.
Comprehensive Assessment
We assess the affected area, surrounding construction, drainage and existing waterproofing details to determine the likely cause of failure and the most appropriate rectification method.
Surface Preparation
Failed membranes, coatings and unsound materials are removed where required to expose a suitable substrate. Cracks, voids and damaged areas are then repaired before waterproofing begins.



Waterproofing Systems
Waterproofing systems are selected to suit the substrate, exposure conditions and requirements of each project. This may include moisture barriers, cementitious membranes, liquid applied membranes and protective coatings.
Rooftop Waterproofing
Rooftop remediation can include removal of failed coatings, substrate repairs, crack treatment and installation of new waterproofing and protective systems. Drainage, falls and penetrations are also assessed where required.
Balcony & Podium Waterproofing
Water ingress through balconies and podiums can result from failed membranes, cracking, poor drainage and defective junctions. Remediation may include removal of existing finishes, substrate repairs and installation of a new waterproofing system.
Planter Waterproofing
Failed planter waterproofing can allow moisture to migrate into surrounding walls, slabs and areas below. Remedial works can include excavation, membrane removal, substrate repairs, waterproofing and coordination of drainage and reinstatement.
Basements & Below Ground Areas
Water ingress through basement walls and below ground structures can occur through cracks, joints and penetrations. Suitable remediation may include crack injection, moisture barriers, joint repairs and associated waterproofing works.
Integrated Remedial Solutions
Larger waterproofing projects often require multiple trades and associated rectification works. Precision Sealing can coordinate these works to provide a complete remedial solution and a single point of contact throughout the project.
