Cambridge

At Thompson Crowley Masonry Inc. we provide professional masonry foundation repairs. 

 Cambridge foundations built from 1638 during early colonial construction to the early 1920's all used masonry and lime mortar for construction. Early period homes from Elliot Square to along the Charles River were built in an orderly grid pattern. 

 Contractors relied on natural resources of ledge, manufactured clay bricks and lime mortar. Portland Cement was not commonly used till 1800's in England and 1900'S in America. Cambridge foundation builders and masons used practiced building techniques of stone foundation bases below grade and brick above grade if budget allowed for it. Fine granite dimensional stone was added above ground exteriors on estate homes or brick. Foundation builders used a hydrated lime, quick lime or hydraulic lime and sand for construction in foundations and plaster. 

Different aggregates were used in lime for strength. Horse hair plaster for interior homes walls and ceilings. A wide array of minerals and specimens were used for foundation construction to add strength to mortar and help in waterproofing.

 Having lime mortar in your foundation its important to use lime based products that react well to existing materials. Using the wrong mortars and sealants are costly mistakes and greatly reduce the life of foundation restoration or basement sealing.

Cambridge homes built in 1600's, 1700's, 1800's and early 1900's having masonry foundations with lime mortar used for construction and basement waterproofing often need repair. Depending on the age of foundation the amount of water the foundation has been exposed to leads to the degree of foundation repairs and restoration. It was very common for local masons to practice lime white washing in basements to maintain basement waterproofing. Perhaps a lost art over the generations which leads to foundation neglect and water damage. 

 Historically lime basements had white coatings and renderings to block out water and seal basements. Ground water over hundred plus years leads to soft, dried out lime and foundation wall coatings falling off.
