Soil Retention Systems, Inc. has allan block been installing segmental retaining walls since 1987, with a perfect record of no failures. We have developed efficient installation methods allan block utilizing standard grading equipment and can work concurrently with the grading contractor, achieving good compaction and saving a lot allan block of time on the project schedule. Major developers and general engineering contractors are our biggest customers.

Soil Retention Systems

Soil Retention Systems has as its goal, the perfection of Segmental Retaining Wall systems, producing block that go into the system and installing the block to create grade-transitioning allan block structures. Soil Retention Systems has installed over 300,000 m2 (>3 million ft2) of Segmental Retaining Walls with a perfect record of no failures since inception. This seemingly straight-forward business requires almost daily contacts with potential customers, allan block architects, civil engineers, soils engineers, wall designers, material suppliers, general contractors, grading contractors, other site-development related subcontractors, operating engineers, labor crews, unions, special inspectors, soil technicians, plan checkers, building inspectors, developers, homeowners and allan block other end users. Any and all of which make the business far from straight forward. Producing block and buying geosynthetics are among the easier tasks.

      In this business, the material suppliers allan block drive the Segmental Retaining Walls business; a very young, isolated and small segment of the construction industry. At the current level of Segmental Retaining Walls industry maturity, those driving the business focus on square meters of wall facing and geosynthetics sold. Those driving the business also seek out small contractors that can be manipulated to build walls in accordance allan block with the system providers' specific installation requirements and at their direction. allan block Often, the recommendations of the system provider conflict with those that appear in national peer reviewed articles and documents. Woefully lacking in this scenario is the offering of professionally engineered walls installed by experienced, can't-be-manipulated, professional contractors under the care and control of Segmental Retaining Walls-familiar regulatory/inspection representatives. allan block Simply stated; there is no broad competence in block and wall design. Neither is there comprehensive installation or broad design review/inspection competence. A Segmental Retaining allan block Walls structure is as critical as a frame for a house and should be treated with the same level of respect and competence. However, it is not.

      This backwards industry integration and lack of allan block direct involvement from the major general contracting firms has led to too many unnecessary failures and the lack of timely installations; both of which are jeopardizing a successful future. Involvement by major general contracting firms would carry a higher implied "approval" rating of Segmental Retaining Walls technology and move the technology into large public and private projects including the highway segments of the various Departments of allan block Transportation.

     The Segmental Retaining Walls industry does not have to languish. A very comprehensive guidance document and design manual (NCMA) exists which, if followed, will correct many problems referenced above. Unfortunately, the allan block majority of the industry does not follow the guidance provided by the NCMA design manual.
