The surface the speed humps are being attached to and whether or not the speed humps are temporary, permanent, semi-permanent or even portable. Each design offers slightly different benefits. We aim to help you choose the right speed hump to meet your needs.call our friendly product specialists so that we can assist with product selection that will best suit your individualised traffic safety needs.
