The concretes, bricks, and natural stones used in construction and masonry work are porous meaning that they allow moisture to penetrate and migrate through the surfaces. However, you can prevent the damages caused by moisture by consulting masonry sealing Auburn contractors to apply sealers on the surfaces. Masonry surfaces such as pavements, walls, foundations, floors, and chimney are designed of mainly porous materials.

Moisture may be caused by many aspects including wet grounds, wet weather ingression, leaky pipes, sewerage backflows, faulty guttering systems, and deteriorated roofing structure. Surfaces designed of natural stone, concretes, and bricks are at risk of cracking and spalling as a result of freeze-thaw cycles. When moisture is trapped inside the construction materials, it causes troubles such as cracks, staining, and increased growth of molds, mildew, and algae.

Structural damages are common in construction materials that are exposed to moisture for a long time. Moisture in premises is brought about by presence of wet grounds where the soils become damp and transfer that moisture to the walls of concretes and bricks. With time, the moisture is absorbed by the concretes and bricks and enters the interior of a building.

Concretes are porous and allow moisture to migrate from one area to another. When moisture infiltrates the concretes, it causes damages such as spalling, where chunks of concrete parts detach from the main structure and crumble down. The infiltration of moisture in concrete walls can spread to other surrounding surfaces such as wooden floors causing similar defects such as swelling and warping of wood flooring.

If you need a brick paving sealer for your patio, it may be different from brick paving sealers for chimneys. However, there are water repellent sealers for all-purpose meaning they can be used in different materials and surfaces. The main reason why you would want to seal concretes and bricks with sealants is to offer a barrier that prevents moisture from penetrating surfaces and preserving the look of those surfaces.

Moisture penetrates through the porous surfaces by capillary action, absorption, and infiltration. With persistent exposure to moisture, the lifespan of the buildings or pavement surfaces is reduced. Leaking pipes in building can also soak the ground and transfer moisture to interiors parts of a building. If you have not installed a guttering system in your building, the water running down the roofing structure pours on the ground next to the foundation and walls of your building.

That water eventually seeps down and enters the basement areas or the crawlspace. Wet weather ingression may lead to leaking of roofing structures that have deteriorated with time. When water enters the concretes, it causes damages like spalling or spitting, something that leads to separation of chunks of concrete from the building structure. In wooden floors, moisture migrating from concretes leads to problems such as warping and swelling.

The acidic substances wear out the chimney liners, concretes, and bricks, and expose other surfaces to the dangerous gases and compounds released from the fuel combusting process. Sealing the brick chimneys can prevent premature damages of these structures thus prolonging their lifespan. By consulting masonry sealing Auburn contractors, you can preserve the quality of surfaces and prevent premature damages caused by moisture infiltration.
