Sealant Applications


Precast panel walls are assembled on site with expansion gaps to allow for expansion, movement and seismic activity.

MPM Waterproofing Services Ltd applies specialist sealants to the joints to provide an external waterproof seal and an internal fire rating.

We only use polyurethane sealants for this work as it is the most flexible sealant and is superior to acrylic sealants.


Concrete block walls also require flexible expansion and seismic joints.  Our sealant systems can provide a flexible, waterproof joint that meets fire rating standards.  The products we use are BRANZ appraised and have proven extremely effective over time.


We can advise on the best products to use for the sealing of external windows, doors and other features depending on construction materials and methods used.  Our experience in both products and their application means you will avoid the leaky building syndrome that in the past was often caused by incorrect product choice and poor application.


We can remove damaged or failed sealants and replace them to current building standards using modern, reliable products.

We use the highest quality Sika and Bostik brands for our sealing applications.
