Keystone

BEAUTIFUL, DRY BUILD RETAINING WALLS WITH HIDDEN STRENGTH

Keystone Montage

The Keystone retaining wall system is the structurally sound, aesthetically appealing, easy-to-install and economical solution to replace Gabion, Crib and cast-in-situ retaining walls. As a gravity wall system, the original Keystone Standard unit provides the weight and stability to resist earth pressures for walls up to 2 metres high.

Keystone offers a wide variety of products with different sizes, shapes, face textures and colours for superior gravity and earth reinforced walls that can rise to heights in excess of 15m.

For all sales enquires please contact our  Customer Service Office at Buxton.
