Why Repairs Aren’t As Bad As You Think

Foundation Repairs – How to Repair Pier and Beam Foundation Issues The Procedure to repair a pier and beam foundation correctly needs a comprehensive inspection of the crawl area. The crawl space is the place beneath the floor which has dock supports, girders, sill plates and joists that will need to be visually inspected for termite damage, dry rot, mold and proper engineering. A Structural engineer ought to be involved in the inspection and repair analysis to insure the appropriate fix is outlined properly. Expansive clay soils may proceed the independent areas of the foundation and crawlspace causing distortion in the structure and leaving indicators of base movement in various degrees. Plumbing leaks and inadequate drainage are leading factors that can influence the clay soils making them swell and undermine the supporting elements of the construction. The repair method is ordered by the findings from the inspection that the engineer outlines in his report. A repair must follow the engineers outline to insure longtime performance of the final result. Utilizing sub grade substances could lead to a failed longtime repair causing expensive future expenses to keep up the foundation.

There are different kinds of pier and beam foundation construction depending on the exterior and interior loads the arrangement is carrying. The dimensions of this girders or beams together with the dimensions of these joists dictate the plan layout of this pier and beam construction. The bigger the joists the farther the girder supports are permitted to be deciphered. The larger and deeper the inside girder supports or piers the further the allowed space between piers.

Ventilation Is critical beneath the floor to decrease the effects of moisture in the timber components and mould. An engineer must include in his report if the venting has to be raised and how many, kind, size and locations of vents to encourage appropriate ventilation. Improper ventilation can result in decreased longevity of the wood elements resulting in future avoidable expense. Drainage correction in areas of ponding water in 10 feet of the structure should be addressed by the engineer. Poor drainage may create the crawlspace region to accumulate standing water especially if the floor surface elevation underneath the floor is lower compared to the exterior floor surface elevation, A french drain is usually recommended to address drainage issues around the foundation where your trying to lower the water table. Pier and beam base are categorized as heavy foundations. They have builders piers under their outside grade beam. The pre-construction piers are installed before the exterior base of the grade beam is poured giving the exterior beam additional support along with a deeper base. Diameter and depths of these piers vary depending upon the loads and geographical places. Most builders piers I have run into on dock bases are connected to the grade beam footing with rebar although engineers recommend to not attach the footing to the piers.
