Masonry protruding entrance water protection


My rear entrance is wood frame set in masonry (brick + terracotta brick) wall. It has aluminum flashing but it's old (way before I got the house) and the top edge isn't protected anymore (since I tore down the vinyl siding to stucco over, which hasn't yet been done), water naturally found its way between the masonry and wood/flashing so I need to devise a solution how this entry can be wateeproofed.

My initial thoughts were to take a 2-1/2 to 3" lintel plate (each side of the L measuring that much) and anchor it horozontally along the top to the brick that can be seen in the first photo using lead anchors in the masonry. That would create that deep a cover over the head piece of PT 2x4 (which will of course also be replaced, along with its flashing) so that the joint between the wood/flashing and brick isn't directly exposed, i.e. has something over it.

Q1: What do you think of the above plan?

Q2: If favorable, should the lintel be installed so...

Just hear me out, you'll see. You'd still use an exterior grade plastic box & matching cover, because you can't get those in metal or any metal that you would want. The matching box & cover are crucial as you need the mounting holes to lie-up & sandwich the stucco on both sides.

Like the box pictured below, you'd screw through its side or back into a stud or blocking. Then, the cover assembly would be caulked or siliconed to the stucco prior to screwing, with Stainless Steel Screws, it to the box.

This, keeps the stucco as an impervious barrier to protect the in-wall box & allows for water to only flow around the separate cover assembly. In the future the cover assembly could be easily removed & re-caulked or siliconed, if needed. Also, bevel the bottom of the stucco opening outward like a windowsill to ensure water can't enter.

Now, the final trick is to cover all of the exposed plastic with a Stainless Steel Blank cover plate with Stainless Steel Screws,...

When installing various water systems and specifically, municipal culinary water systems, engineers tend to focus on two main points, 1) designing an efficient system and 2) protecting that system against potential problems.

What Is Water Hammer?

One major problem that causes severe damage or system failure for any water treatment station is water hammer shock waves. “Water Hammer” or “Hydraulic Shock” is a pressure surge or shockwave resulting when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). The reversed momentum then continues to multiply the further it travels before being stopped.

The air cushion provided by a hydropneumatic tank absorbs the shockwaves from water hammer.

Cause & Effect

This pressure wave can cause major problems, from noise and vibration to pipe collapse and total system failure. If the...

What is Stormdry Masonry Protection Cream?

Stormdry is a deeply penetrating water repellent cream for brick, stone, and concrete. Due to its cream-based formulation it is able to penetrate more deeply into masonry than standard liquid-applied water seal products.

Stormdry is based on proven silane/siloxane technology and works by lining the pores of the masonry rather than blocking them - allowing the wall to continue to breathe. This is in contrast to many standard brick sealer and stone sealer products which coat the masonry with a thin film.

Stormdry is easy to apply using a brush or roller and only a single coat application is required - many competing water repellent products require two coats.

25-Year Durability

Stormdry is the only colourless masonry water repellent treatment that carries BBA approval (cert. number 15/5198). After extensive testing to determine continued water-repellency after aggressive freeze-thaw and UV exposure, the...

A mason laying mortar on top of a finished course of blocks, prior to placing the next course.

Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term masonry can also refer to the units themselves. The common materials of masonry construction are brick, building stone such as marble, granite, travertine, and limestone, cast stone, concrete block, glass block, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer.


Masonry [1] is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either weight-bearing or a...

Water is the single most damaging element to masonry in our environment. Even in a short period of time, water can deteriorate and stain unprotected masonry. Rainwater dissolves natural salts within masonry that recrystallise when the surface dries. After repeated wet/dry cycles these salts build up, creating internal pressure that weakens the masonry. Rainwater that contains atmospheric pollutants (acid rain) chemically further weakens the substrate.

These factors, interacting with other natural forces, eg temperature extremes and biological growth, may result in structural and aesthetic damage, such as:

Cracking, spalling and delamination of masonry surfaces due to freeze/thaw cycles. Efflorescence Lime and rust staining Damp walls Mildew, moss and lichen growth Chemical corrosion from acid rain Reduced thermal insulation

Protection can be applied to:

Brick Terracotta Tile Cast stone Granite (polished or unpolished) Limestone (polished or...

Water source protection involves the protection of surface water sources (e.g. lakes, rivers, man made reservoirs) and groundwater sources (e.g. spring protection, dug well protection, and drilled well protection) to avoid water pollution (see also pathogens and contaminants).

While surface water sources and springs are directly exposed to human activities, groundwater sources are often protected through overlaying soil layers. However, accessing groundwater sources through dug or drilled wells allows contaminants to enter aquifers, polluting the well itself and the water in nearby lakes, rivers, or neighbouring wells, which consequently threatens both public health and the environment (MANCE n.y.).

In the past, the need for water source protection has often been neglected. As a consequence, many drinking water sources have become contaminated making water purification measures indispensible. The very slow flow of groundwater makes rehabilitation...

Division 4 Masonry

Williams Masonry Control Joint materials are made of quality elastomers, meeting ASTM material standards. These control joint gaskets provide more than one functional feature for a given application. These custom designed seals furnish an excellent seal and function as a second line of defense when sealants fail from in-service use. These sealants will shed water and will reduce sound and thermal transmission. Shear loads from wind are transferred to the concrete masonry units with our gaskets in control joints.

DRYLOK® Extreme Masonry Waterproofer may be applied on a slightly damp surface, but best results are obtained when the surface is dry, clean and free of grease, oil, form-release compound, and paint. Remove dust, dirt, and any loose or broken mortar with a wire brush. Old paint in poor condition should be removed by wire-brushing, sandblasting or other suitable methods.* If you see white, powdery, crystal-like deposits on the surface, they are naturally-occurring, water-soluble salt compounds in the masonry, pushed out by water intrusion. When the water evaporates, the salt residue remains. This effect is called efflorescence and, because it prevents DRYLOK® Extreme Masonry Waterproofer from properly bonding to the surface, it must be removed. Treat it with DRYLOK® Etch** (liquid or powder formula) or muriatic acid according to the manufacturer's directions, rinse, and allow the surface to dry. Since efflorescence occurs naturally, we cannot warrant against it...
