Heavy Duty Deckin’ Block



Our engineered decking block was designed as a simple but highly effective, stable solution to DIY decking.

These Heavy Duty Decking Blocks are perfect for larger projects such as Hot Tubs and Garden Buildings. They make building a deck fast and easy.

We have incorporated drainage channels to protect the timber joists, a strong footprint for complete stability and cast in high strength concrete to give weight, the integral part of any foundation.
