Alfablocs divide up waste

Kent-based TW Services recently doubled its operating space with the opening of a 10-acre facility in Sandwich.

All the bays were constructed using nearly 500 Alfablocs, supplied by retaining wall specialist Poundfield Products of Ipswich.

The operation, which now has the capacity to handle up to 750,000 tonnes of waste a year, first used the reinforced concrete Alfablocs in 2003. It now has some 1,200 in place, with the original units still in constant use to segregate inert and hazardous waste streams.

Spencer Ray, managing director at TW Services, says: “When we first used Alfablocs, we realised they suited our requirements perfectly and, over the years, we have used them for more and more applications, from storing lightweight recycled products to unprocessed concrete.

“They have stood the test of time in the harshest of environments, and so were our preferred solution when we set out to build our new facility.”

Poundfield’s Alfabloc retaining wall system is designed to be freestanding in most cases. They are available in heights from 1.22m to 6m. Individual units are bolted together using galvanised metal plates, which help to spread horizontal loads and prevent material transfer when loaded on both sides.
