Impact-echo is based on the use of transient stress waves generated by elastic impact. A diagram of the method is shown in Figure 2. A short-duration mechanical impact, produced by tapping a small steel sphere against a concrete or masonry surface, is used to generate low-frequency stress waves that propagate into the structure and are reflected by flaws and/or external surfaces. This is the home page's excerpt. We can repair, replace or restore your bricks, block, stone or cement. Providing complete stone retaining wall services, stone foundation repairs and . The book is packed with more than illustrations and a wealth of new, detailed examples. This state-of-the-art guide features strength design philosophy for reinforced masonry structures based on ASCE design loads for wind and seismic design. Retaining walls are made of reinforced concrete, timber, stone or bricks, depending on the level of protection needed. Retaining walls are also used to support terraced gardens and similar structures. Often, steel sheet piling is required for retaining walls, and contractors such as Sheet Piling UK are needed.

With the land consistently sloping toward the Gulf and periodically overrun with water, it's easy to see why retaining walls are a common phenomenon, especially as you move closer and closer to Galveston and its famous sea wall.
Retaining Walls. During construction work, masonry walls (brick or block) can fail due to side loads on the walls, the rate of construction, inadequate foundations or adjacent excavations.
Side loads may include wind, inadvertent impact with the walls or leaning materials against them. Such failures can result in. lock walls; guide and guard walls; and submerged retaining walls and other structures used for flood barriers, conveying or storing water, generating hydropower, water borne transportation, and for restoring the ecosystem.
