DESIGN INNOVATION: Gravix retaining wall system was created to meet the demand for minimal excavation requirements. The brief was to design a wall that was almost vertical which would be able to accommodate the surcharge loadings from cars and small lorries. NO LOAD ZONE Some minor intrusion into the pipe protection envelope may be permitted where the pipe protection envelope abuts the property boundary. While looking at national averages can give a general idea, such numbers usually do not include factors which may affect the final price, such as local labor hourly rates, material costs and any local permits required for the Mesa retaining walls project. A three foot wall installed within three foot of a structure such as a house will have a surcharge from that structure. You may have the rock on your lot or land like I do. 10) Light Traffic is auto or empty pickup truck loading. Surcharge loading means a load applied to a soil stratum that has, or may have, the effect of consolidating the stratum, other than a load arising only from— o persons or vehicles on, or moving over, the stratum; or o the effects of rain on the stratum. By their nature, retaining walls are intended to be relatively maintenance-free structures once they are constructed. It represents all transportation modes, including air, highways, public transportation, active transportation, rail, and water. Models have been developed to represent the horizontal load surcharges on abutment walls, wing walls and other earth retaining structures due to traffic loads. What is a surcharge load?.
