ProtectaWeb™

Slope stabilisation

ProtectaWeb slope stabilisation system has been designed to prevent shear failure and lateral movement of aggregate materials. It works by stabilising the infill, providing load distribution over weak soils, and base stabilisation for paved and unpaved roads.

Protecta Web product render

ProtectaWeb slope stabilisation provides contractors with straightforward installation, even on steep banks and slopes. A perforated panelled system, ProtectaWeb is an incredibly cost effective solution for stabilisation and can reduce granular fill requirement by up to 50%.

Common fill materials can be used, even in locations of high load intensity. When infilled, ProtectaWeb provides a semi-rigid foundation.

Traffic loads are distributed laterally, reducing rutting and assisting in the retention of infill materials.

The Kinema in the Woods

The Kinema in the Woods is a cinema in the village of Woodhall Spa, Lincolnshire, England. Dating back to 1922, this beautiful woodland setting is a protected conservation area.

 

Wrekin Products were invited to assist with creating a new access road and car park in the sensitive area in which the cinema is located and which is surrounded by hundreds of trees protected by Tree Preservation Orders (TPOs).
