GRP LATTICE MATS

The composite solution for reinforcement.

Structural elements often need to be restored or even replaced due to corrosion damage to the steel reinforcement, which leads to destruction of the concrete structure. This applies in particular to components that are exposed to road salt. With the use of GRP reinforcement, corrosion is a thing of the past. It drastically reduces the number of component repairs needed. GFRP reinforcements are mainly used for concrete and polymer concrete components.

The same advantages as for plastering walls also apply to plastering ceilings. Here, the improved adhesion of the plaster is even more important.

GRP mesh grid mats are also ideal for large-scale fencing. In addition to their low weight, they are also very weather-resistant and maintenance-free.

GRP grids are weather- and UV-resistant. They do not rot. It's not necessary to replace the grid after just a few years.

Choose the grid colour to match the substrate or the colour of the plants.

Open ponds are always a potential source of danger for playing children or animals.

One solution is to secure your pond with a sturdy GRP grid directly under the water's surface. With a suitable colour, the grid remains largely invisible.
