Adding Weep Holes It is clear that not only does the building not contain any weep holes at the shelf angles and flashing, but that sealant was placed in front of the angle. Water that penetrates the masonry walls and flows down the cavity cannot leave the wall because of this sealant.

Retaining wall Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer. This construction technique tends to be employed in scenarios where sheet piling is a valid construction solution, but where the vibration or noise levels generated by a pile driver are not acceptable.

- Sloping involves cutting back the trench wall at an angle inclined away from the excavation. Shoring requires installing aluminum hydraulic or other types of supports to prevent soil movement and caveins. Shielding protects workers by using trench boxes or other types of supports to prevent soil cave-ins.

- Openings in interior and exterior bearing walls require lintels or arches. Arches and lintels are both common on exterior masonry walls. Lintels are almost exclusively used in interior wood walls and exterior wood frame walls with siding.n a masonry wall, the arch or lintel carries the weight of the masonry immediately above the opening. However, if you draw two lines up toward each other from the top corners of the opening at 45 angles, you'll end up with a triangle.

- A building permit is required prior to the installation of exterior siding or stucco. A building permit is. not needed for small repairs to existing exterior sidings and stucco, provided the repairs are limited to no. more than ten square feet of wall area.

- The two holes you see in the water pump casting are called weep holes. The upper weep hole acts as an air vent. It allows air to evacuate the casting system and prevents the build up of humidity around the bearing. Also the vent allows atmospheric pressure into the pump and the seal remains seated. The lower weep hole exists to allow fluid to collect or drain out of the water pump to protect the bearing integrity. In a horizontal centrifugal pump there is little space between the bearing and the seal so fluid build-up could potentially threaten the bearing.

Quoin Stone quoins are used on stone or brick buildings. Brick quoins may appear on brick buildings that extrude from the facing brickwork in such a way as to give the appearance of uniformly cut blocks of stone larger than the bricks. Where quoins are used for decoration and not for load-bearing, they may be made from a wider variety of materials beyond brick, stone or concrete, extending to timber, cement render or other stucco

Earth Buildings and Their Repair Chimneys are usually constructed of brickwork above the roof, although the flues below are often of clay-lump. Where there are no chimney pots, water is liable to get inside the chimney and erode the top of the clay-lump. Many brick flues were lined with subsoil and some had their brickwork laid in earth mortar.Openings in walls are bridged with wooden lintels and often have blocks of wood built into the reveals for fixing doors or windows.

- Typical Brick Cavity Wall Details Brick Cavity WallA cavity wall consists of two wythes of masonryseparated by a continuous air space that isbetween two and four inches in width. The cavity wall is utilized because it is an excep-tional all-weather wall. Because of its ease ofinsulation, it is an efficient energy saver.

- The selection of the wall type by the designer. is very important. It is easier to install a water. resistant barrier in some walls than in others. Drainage walls are walls with a cavity for the downward flow of water that has. breached the masonry veneer. These walls are the best type of walls to design for. resistance to interior water penetration. Barrier walls are the most difficult to design for resistance to interior water.

Borehole Typically, a borehole used as a water well is completed by installing a vertical pipe (casing) and well screen to keep the borehole from caving. This also helps prevent surface contaminants from entering the borehole and protects any installed pump from drawing in sand and sediment.

Advantages of a Brick-Exterior House Apart from occasional drainage problems, brick homes are easy to maintain. According to Siding Helper, for the first 25 years, brick homes only require an occasional wash with a hose. After that, loose or chipped bricks may need repairs. Brick-home owners won't need to worry about painting or decay.

Coping questions For this reason, many architects recommend using a continuous flashing membrane beneath the metal coping. This membrane covers the top of the masonry walls and roof base flashing so any water leaking at splice joints in the metal coping is prevented from reaching the top of the masonry wall below. This flashing or roofing membrane can be fairly thin because it is protected from the elements by the metal coping.

- Weep holes permit this coolant to evacuate the system and protect the bearing. Weep holes also allow atmospheric pressure into the pumps and help the seals to remain seated. Does a drip from the weep hole mean seal or pump failure? Perhaps. Seals will drip as the seal lap in but to understand a more prolonged or intermittent “drip” you have to understand a seal’s design.

Cavity wall This water will also be adsorbed by the masonry and must therefore be able to dry. The cavity serves as a way to drain this water back out through weep holes at the base of the wall system or above windows. The weep holes allow wind to create an air stream through the cavity. The stream removes evaporated water from the cavity to the outside.

- BRICK VENEER CONSTRUCTION. A brick veneer wall is constructed by having a non-structural external layer, usually with bricks and it. is backed by an air cavity. The innermost element of this type of wall is structural can consist of wood, metal framing or. masonry. A brick veneer construction has many advantages over solid masonry.

Brick Arches Being wider at the top than at the bottom, these ‘voussoirs’, as the units are called, cannot fall out. However, in the case of a rough arch, it is the mortar which is tapered, not the bricks, and the arch relies on the cohesion of the bricks and mortar for its strength.

Why Your Basement Needs Window Wells (and Well Covers, Too) When you install a window in such a basement, you need to dig a well on the exterior. The well is your opening to the outside world ​so that the window can bring in some measure of air and light. In some cases, these wells must be of specific dimensions in order to allow for exit in case of emergency.

How to Install a Foundation Vent Installing a foundation vent requires drilling into the masonry wall. Moisture can accumulate in a crawlspace as a result of leaky plumbing, inadequate yard grade or even a lack of guttering and downspouts.High humidity is a concern because it can lead to mold growth on the joists and can loosen subfloor adhesive. If the distance from the bottom of the sill plate to the soil is less than the width of the foundation vent, you’d be better off installing a vent in the rim joist. 2  Installing a foundation vent too low can add to the moisture problem by letting ground water drain into the crawlspace.
