Roof Repair - Waterproofing Solutions from Belzona Technosol Limited

In May 2011 Belzona Technosol Ltd completed an application for the Ministry of Defence. The client contacted Belzona looking for a waterproofing solution as water was penetrating into their flight operations building.

On initial inspection it was found that there were three areas of concern, a leaking roof, some damp external walls and damaged expansion joints.

Belzona Technosol Ltd undertook the initial surface preparation to remove loose debris and plant growth from the roof areas. The three roof areas totaling 100m2 were then coated with a cold applied liquid roofing system specially designed to be weather tolerant during inclement conditions. Impressively, it will not suffer washout if rained on immediately after the application.

In addition to the roof leaks, two areas of external wall were found to be suffering from water penetration into the inside walls causing damp areas.

To reduce further maintenance costs, Belzona 5122 (Clear Cladding Concentrate) was selected as a cost effective solution to the damp external wall areas. This product is a clear water repellent treatment for masonry surfaces designed to prevent water penetration into the building fabric.

The third application area of concern to the client was approximately 96m of damaged expansion joints. These we removed and replaced with Belzona 2211 (HI Build Elastomer). The highly elastic material was simply applied by hand providing great adhesion to the concrete substrates ensuring a long term flexible seal to the joint.

Belzona Technosol Limited has extensive experience in the field of repair and maintenance of machinery, equipment, buildings and structures. Belzona is able to offer solutions to problem areas such as erosion corrosion, chemical attack, abrasion and wear, water and weatherproofing, safety surfacing and a myriad of other situations.
