Masonry reinforcement, anchor bolts, plastic mountains and much more from the companies that make those all-important structural products. Plus, restoring Camden's Roundhouse and industry news
Refurbishing the Roundhouse
Weber SBD's epoxy resin repair system Epoxy Plus has been used to restore the roof timbers at the Roundhouse, a performance venue in Camden, north London. Quadriga, a conservation and restoration specialist, carried out the refurbishment of the 1846 building, which is grade II*-listed. The project involved drilling and pinning fractures and shakes in the timber with stainless steel dowels in conjunction with injections of Epoxy Plus. This consolidated and sealed the shakes and restored the structural integrity of each member.
Polyethylene sub-base course
Delta Membrane Systems has launched a sub-base course designed to be a cost-effective alternative to lean concrete courses. It is called Delta-MS, and it is a dimpled sheet made from high-density polyethylene and it is said to be resistant to acids, alkalines, oils and solvents. The maker says the product also protects the foundation slab from rising damp and prevents cement grout from seeping into the ground. Delta-MS is available in 2, 2.4 and 3 m wide rolls in lengths of 20 m.

Super-strength masonry reinforcement
BRC Special Products has redesigned Bricktor CCR, its masonry reinforcement product, to make it stronger. The woven stainless steel mesh has been replaced with a welded format. The maker says Bricktor CCR is suitable for bonding and strengthening brickwork, blockwork and stone walls and can lie flat on the masonry mortar joint, making it easier to install than other coiled products.

Shear load connector
Fixings supplier Halfen-Deha has launched a shear load connector called CRET that transfers shear forces across structural joints. The company says it facilitates the structural movement caused by temperature change, shrinkage and creep without the need for corbels and double supports.
Larger precast concrete pile
Centrum Pile, a maker of reinforced precast concrete piles, has added a 400 mm square section pile to its standard range. This larger section is said to be suitable for applications such as the foundations of land-based wind turbines. The company claims it is the largest factory-produced precast concrete pile available in the UK.
All-purpose anchor bolt
Fischer Fixings has launched a zinc-plated steel anchor bolt called FAZ II for use in both non-cracked and cracked concrete. The maker says the general-purpose anchor bolt is suitable for applications including the installation of beams, railings, banisters, brackets, machinery and steel fabrications or stairs. FAZ II is available in a range of diameters from 8 to 16 mm.
Loadbearing structural board
Marley Eternit has launched Duripanel, a loadbearing structural board that can be used as an alternative to chipboard or plywood. Duripanel, a cement-bonded particleboard, is suitable for applications such as roof decking and acoustic or high-impact lining.
Monumental plastic mountain
GE Plastics has supplied 550 m2 of its Lexan Margard transparent plastic sheet to the Giant's Tooth, an 8 m high monument built in Turin to celebrate last month's Winter Olympics. The monument, named after a peak on the border of Italy and France, was designed to resemble an ice-covered mountain with vertical rock formations and a central spire. The company says the product is about half the weight of glass, resists abrasion and can be frequently cleaned without causing damage.
Tough yet light floor joist
Timber products specialist Scotts of Thrapston has developed Easi-joist, an engineered floor joist that is said to prevent warping, bowing and general distortion. The maker says that Easi-joist combines the lightness of timber with the strength of metal and that the open web system allows for the easier installation of services such as 100 mm soil pipes and water pipes.
