Frost Heave Protection Ice Build-Up Can Be Dangerous Ice buildup or frost heave in the ground can cause structural problems such as uncontrolled movement of the tank, leading to serious leaks or worse. The boards are manufactured in a range of thicknesses to meet the application – Beam, Slab or Insulated Slab The amount of frost heave can be tremendous. Establish-ing the proper design, procurement and installation of materi-als for a project will ensure a successful heat tracing system installation. When dry, the boards have a compressive strength that can support concrete and steel up to 1 meter thick without deflection or creep compression. Plan where you want the fence posts and then call the utility companies prior to digging the first hole so they can mark where gas and electrical lines run. As new airport and runway construction expands worldwide, they must often be located on marginal or swamp land that is extremely subject to soil heave and ground movement due to freeze-thaw cycles. Frost damage to building foundations, retaining walls, driveways, walks and similar structures is common throughout Canada, and although it is not equally serious in all areas the resultant cost each year is high. TuffTrak ground protection matting products include mats which are compression moulded, compression moulded with overlap, cellular core with overlap, and lightweight overlap with a conical underside. The resulting pressure heaves the fence posts out of the ground over time. Prevent problems with ground heave: speak to the team at Precon today. CBD-26. HEaVE PRECaUTIONS deep trench fill foundations in clay soils within the zone influence of trees will require protection from vertical and lateral clay movement on the sides of the foundations, substructure walls and under the ground floor construction - even if the trees have been removed. TuffTrak Heavy temporary access and ground protection matting consists of a range of products to suit every construction, infrastructure, utilities, or events project. As an integral part of the Cordek Cellcore ground heave system, they aid installation by fitting securely around the pile and providing a square edge for the Cellcore panels to be butted against. Cost? It is consisted of specially moulded hexagonal cellular Filcor expended polystyrene, available in a number of different depths and grades. frost heave protection by maintaining the ground temperature above freezing. Vertical ground movements of 4 to 8 inches are common and as much as 24 inches have been reported. Common signs of ground heave. Frost Heave Protection Ice Build-Up Can Be Dangerous Ice buildup or frost heave in the ground can cause structural problems such as uncontrolled movement of the tank, leading to serious leaks or worse. *When the analysis exceeds 60 or the shrinkage potential is greater than High, please consult the Cordek Technical Team on 01403 799600 for further information. Perfect for clay heave protection for mini piling, underpinning and basement construction; Heave Stopper Details. These pipelines would be subject to frost heave where unfrozen pockets of ground referred to as taliks occur.

Lemon are proud to be the UK’s largest Cellcore supplier, and the UK’s largest Clayboard supplier. This produces an extremely cohesive soil type when wet, but shrinks to a crumbly, crazed structure when dry. Trench fill foundations deeper than 2.5m will only be acceptable where they are designed by an Engineer (see Technical Requirement R5).
