Most face brick have holes to help the units fire properly, promote bonding with mortar, reduce overall weight, and make them easier to handle. Solid brick are used where holes may be unsightly, for example, in steps or window sills. Pine Hall Brick manufactures brick in the following sizes:
There are 7 modular brick per square foot and 5.8 oversize and queen brick per square foot.
The surface texture of brick is very important to its overall appearance. Identically colored brick can look dramatically different simply by adding texture. There are a variety of textures available including wirecut and torn face (rough texture). Texture can also be created by applying coatings, machine made impressions, or other mechanical treatments.
The distressed and uneven textures frequently seen in handmade and wood mold brick can be simulated at a less expensive price by mechanical treatments. Mechanically treated extruded brick sometimes known as "tumbled brick" may have superior structural properties when compared to handmade and wood mold brick.
Tumbled and Rumbled Brick
Tumbled Brick are brick that are tumbled down a ramp prior to the firing process that gives the brick a “no-two-are-the-same” handmade look with the properties and color selection of today. Rumbled Brick are brick that are tumbled down a ramp after the firing process that gives the brick a weathered old world look with the properties and color selection of today.
The color of brick is determined by the raw materials it contains and the method used to fire it. Additives blended into the clay mixture can create color completely through the brick body. Sand coatings, ceramic slurries and other additives can be applied to the face of the brick to create different surface colors. Changing the firing temperature will also produce different shades of color from the same raw materials. Flashing is one method of firing brick which burns some of the brick darker. These flashed brick add color range and highlights to many styles of brick.
Mortar represents approximately 20 percent of the total surface of a wall, so picking the right mortar color is very important to the overall look of your home. Different mortar types and specifications are required for various applications and climates. The most common is called type S and is naturally gray in color. Mortar can be tinted to blend or to contrast with the brick color. It is important to keep mortar mixing and tooling practices uniform, especially when using colored mortar. A slight variation in mortar color can have a dramatic effect on the appearance of a finished wall. Pine Hall Brick stocks a variety of colored mortars for you to choose from. Your salesperson can discuss the mortar colors that look best with your brick color. Also, sand color will affect the finished look of your mortar color. Lighter color sands are generally recommended for lighter colored mortars. Inquire about the common sand colors in your area. ¨The mortar joint is also an important factor in the appearance and functionality of the wall. "Tooling" the joints help seal the wall surface against moisture penetration. The concave, vee, and grapevine joints are best for exterior construction. These joint types compress the mortar at the surface and are the most weatherproof. Other joints are acceptable for interior use.
Mother Nature did not make soil and clay consistently one color. When manufacturers mine raw materials, the clay and shale composition will change slightly as the mining location shifts. This subtle change creates a color variation each time the clay is fired and helps give brick its warmth and character. So, every run of brick (any color) varies somewhat from the last run and can vary dramatically over a period of years. Plus, brick will weather in the wall and as a result it is impossible to accomplish a perfect match when adding on to an existing building, but we can generally get close. Consult Pine Hall Brick for help in matching your existing brick.
The Four Basic Steps for Proper Brick Cleaning are:
1. Remove all excess masonry particles with a masonry tool or fiber brush;
2. Use plenty of water and thoroughly soak the wall;
3. Use the recommended cleaning product and carefully follow directions;
4. Rinse the wall thoroughly with water. Some brick cannot be wet cleaned. Check the brick tag or with the brick manufacturer for any special instructions before you begin cleaning.

We recommend a base layer of 4” of compacted crusher run gravel (8” for a driveway) and then a setting bed of 1” of concrete sand (not masonry sand). This should provide a long-lasting stable base for your pavers. Laying pavers directly on the ground is not recommended.
Clay paver color is permanent. Sealers are not recommended or necessary for long-term durability or color stability. In fact some sealers can actually harm the performance of the system.
Moss & Weeds
The existence of moss is an indication of poor drainage (in a shaded area) as the saturation of water creates an ideal environment for growth. The best solution is to keep the area dry by improving drainage or elevation although these remedies may not be practical. For moss and organic growth removal, a three-to-one solution of water and chlorine bleach is recommended or a one to one dilution in severe cases.
Weed growth in flexible base paving systems is common in lower traffic areas. Contrary to popular belief, growth takes place in the sand joint and not from underneath the pavers. Weed killer such as Round Up will handle existing growth while a pre-emergent weed killer can be used in the spring as a prevention measure.
Joint sand is the key to providing interlock between pavers and providing cushion between the pavers to prevent paver-to-paver contact and chipping. The sand joint between pavers should be between 1/16” and 3/16”. Concrete sand that has course and angular particles is recommended over mason sand which has rounder finer particles. The joints need to be completely full of sand to function properly and promote interlock in the system. If the sand joints between your pavers are not full then it is important to add more sand to prevent pavement failure. A proper installed base and edge system that drains properly will go a long way towards maintaining full joints.
Joint Sand Stabilization
For the vast majority of applications we do not recommend using joint sand stabilization products. If you do decide to use a joint sand stabilizer, we typically recommend moisture activated joint sand stabilizer and cannot stress enough the importance of the pavers being completely dry and the pavers being sweep and blown completely free on any residual stabilizer prior to activating the product.
We do not recommend a portland cement and sand mixture because the cement tends to get stuck in the small crevices of the pavers and subsequently stain. Efflorescence is also a concern when using a portland cement and sand mixture.
Efflorescence is a crystalline salt deposit on the surface on the pavers that is caused by the migration of contaminated water through the pavers that result in a white or gray powder on the surface of the pavers. The most common source of efflorescence is the use of deicers like rock salt. If you are going to use a deicer we recommend pure magnesium chloride as it will not cause efflorescence.
The simplest remedy to efflorescence is to allow the efflorescence to run its course provided that the paved area has good drainage. In a flexible base application, after 6 months, 90% of the water will run off the paving surface and away from the pavers versus down through the joints. This change should help carry the salts in solution away from the pavement. In all cases, free salts dissipate eventually and the problem goes away for good, generally within 18 months.
Efflorescence can also be removed quickly by dry brushing and then vacuuming up the powder or with clear water and a stiff brush. The crystals are superficial and do not affect the durability of the pavers, but may reappear.
Pressure washers are not recommended for use on flexible base applications. The pressure washer tends to remove joint sand which compromises interlock. We suggest using a stiff application brush and a normal pressured garden hose.
Removing Stains From Pavers
For general cleaning, we would recommend EaCo Chem's NMD 80 or SureKlean 600. Do not use muriatic acid as the acid concentrations can vary from container to container and higher acid content can produce more stains.
The cardinal rules for cleaning brick are to always pre-test a small area first (preferably in a hidden area), pre-wet the area with water and follow directions carefully.
Sand Set vs. Mortar Set Paver Systems
Both systems have their own unique beauty and appeal. Sand set paver systems are cheaper to install than mortar set paver systems and are also much easier to install. Both systems are durable for many years when installed properly, but sand set pavers have better long-term system durability than mortar set pavers because the mortar joints will break down and create weaknesses in the system over time.
Brick are usually priced per thousand units. Pavers are usually priced per square foot or per thousand.
Order & Delivery
Delivery to your job site depends on the availability of the brick and of the delivery equipment. Normally when a brick is in stock, delivery to your job site should be within one to three working days. There is a $75 delivery fee for orders less than eight cubes.
Pine Hall does not pick up or accept brick/pavers for return once they have been delivered. When exceptions are made, any products returned will be subject to a pallet/cube restocking charge. No brick/pavers can be returned in less than full pallet/cube packages
