PERMACRIB Timber Crib Retaining Wall System offers a number of distinct advantages.EconomyWhile providing an excellent engineering solution and a visually attractive appearance, Permacrib also offers significant cost advantages over other systems. Finished wall costs generally range from $180 - $280 per m² for heights of 1.0m - 4.0m. Above 3.0m - 4.0m heights Permacrib walls become exponentially cheaper than other options.Aesthetics / EnvironmentalManufactured from NZ’s renewable forestry resources, Permacrib provides an environmentally attractive and natural timber finish. Compared to other timber pole and block retaining wall systems Permacrib has a far softer appearance. This can be even further enhanced (at modest additional cost) with the use of our topsoil filled Geotextile Planter Bags which allow selective planting directly into the face of the wall. This ability to permanently support vegetation affords Permacrib great versatility over a range of landscaping options.Ease of ConstructionPermacrib construction is simple and can be undertaken by any competent builder or even home handyman. For larger or more complex walls there is a network of experienced Permacrib contractors nationwide.125 Year Design LifeTreated to H5, Permacrib has BBA approval to 125 years and NZ’s Forest Research Institute has concluded …“that the in-service life of Permacrib will be indefinite. Certainly, the performance data indicates that a life of 125 years can be expected.” All Permacrib timber components have a 50 year warrantee against decay and termites.Free Design Service & Technical SupportMost Permacrib walls constructed in NZ are being designed and costed free of charge by Phi Group for Consulting Engineers, Architects and Clients.
