3 Essential Tips for Core Drilling on Your Own

Core drilling refers to rounded drilling through the core of cement, concrete, masonry, brick, and stone. This type of drilling usually involves special drill bits that cut round and hollow openings in these materials, for running plumbing pipes, electrical wiring, and the like. If you’re going to be doing some core drilling on your own, note a few essential tips from the pros to make it easier and more effective.

1. Less water

When using a wet drill, keep in mind that less water is better. You may be tempted to use more water to keep the drill cool, and this is of course essential, but diamond drills work better when they can wear down so that new diamond tips are exposed. If you use too much water, there won’t be enough friction against the drill bit to expose the harder diamonds underneath, and you’ll be drilling with a worn and soft bit. Use just enough water to control heat and dust, and no more, and your drilling will go much faster and be more accurate and effective.

2. Draw an outline

When using a core drill, you need to ensure you drill directly through the material or your core will angle up or down. This can cause a problem for plumbing pipes, as this might interfere with water flow. It may also make it more difficult to thread electrical wiring through the core. To help you keep your drill even, draw an outline of the drill bit on the wall or other surface before you drill. Watch the outline as you gently guide your drill through the wall,rather than the drill bit. This can help you to concentrate on keeping the drill level and even as it makes its way through the surface.

3. Increase the bit depth slowly

Core drill bit extensions can allow you to drill the core through the wall or floor easily, but you want to increase this depth slowly. Since you typically cannot see the other side of the surface through which you’re drilling, it’s important that you use the right depth of extension. If you cannot measure the depth you need easily, increase the depth slowly, one inch or centimeter at a time. Remember that you can always continue to drill if the bit doesn’t reach deep enough, but if you drill too far, the patch or repair work can be difficult if not impossible. Don’t be overeager when it comes to drill extensions, but take your time to ensure you drill as deep as needed but no deeper.

Three Types of Concrete Joint Sealing Products

Concrete is a valuable building material because it is resilient, durable and versatile in terms of potential applications. In addition, there are diverse design options for concrete since the material can be coloured, stained and even textured to produce varying visual effects. However, you should note that concrete structures require some maintenance for continued quality performance. This is particularly important if you have installed a concrete driveway or sidewalk in your property.

Generally, these surfaces are constructed with expansion joints which allow proper enlargement and contraction depending on temperature fluctuations. If the joints are neglected, they will allow moisture to flow under the slabs causing structural damage. Concrete joint sealers are soft materials which are filled into the space to prevent intrusion from water and dirt. They do not limit expansion and can improve the surface appearance. Here are the main types of concrete sealers available in the market.

Liquid Sealants

As implied, liquid sealants are purchased as fluid products which can flow easily into the expansion joints. They can be purchased in local stores and they are typically packaged in tubes and even pails. The material can be applied using a nozzle or you can obtain a backer rod to control the seepage of the sealing fluid. The main benefits of choosing liquid sealants are the ease of application and the relatively low cost of purchase.  Good products such as high-quality silicone sealants will provide watertightness, resistance to UV degradation and long-term service.

Impregnated Foam Sealants

Impregnated foam sealants are made using cellular polyurethane. The process involves impregnating or filling up the foam cells with water repellent adhesive compounds. The material is compressed to provide a compact sealant product which can be placed directly into the expansion joints. You can purchase the preformed and pre-compressed foam sealant as finished products from building material stores. The main advantage of choosing this type over the liquid sealants is that the foam provides thermal insulation in addition to moisture non-permeability. This reduces the probability of cracking due to sudden temperature changes.

Hybrid Sealants

Hybrid sealants are manufactured by combining the properties of both the liquid and impregnated foam sealants. Basically, the products are designed and produced by applying silicone fluid over a polyurethane foam backing. The foam provides the secure anchoring between the joints, thermal insulation and resilience against the movement of concrete. The upper liquid sealant provides stability and durability because it can fold and unfold without extensive stress or allowing penetration by moisture.

For more information on sealing your concrete, you can contact a concrete construction company like Allied Concrete Cutting & Drilling Pty Ltd.

Important Factors to Note When Buying a New Carport

A carport can protect your car as well as any RV, ATV, lawn care equipment and anything else that needs some protection from the elements. They’re a very affordable alternative to a garage, or they can be installed on a property in addition to a garage. They can even be used as a patio area for outdoor entertaining. Before you buy a carport, note a few important factors to consider and to review with the installer so you choose the right style and know what to expect. 

1. The roof type

The roof type you choose will be determined by your budget and the level of protection you need for items stored under your carport. Most standard roofs are two simple panels that curve at the frame of the carport. This type of roof may be the most economical. A more costly option, but one that offers more protection, are roof panels that are connected to the frames and which don’t have sloping ends. These allow water and other debris to slide off the roof and away from the carport, whereas the roof style with curved sides allows the water to run by the sides of the carport.

When choosing a roof style, you also want to note the direction of the ridges. These can run side to side or back to front; if the carport is installed right next to your home, you may want water to run off the front and back of the carport versus the sides.

2. The cement pad

If you’re going to be pouring cement as a pad for your carport, be sure you ask your installer or the company from which you purchase your carport the measurements needed. In some cases the pad must be smaller than the actual dimensions of the carport, so the frame can be placed in the soil and not on the pad itself. In some cases, a carport can be installed over concrete, but it may require special anchors and this may be an additional charge.

3. What upgrades can be added?

Don’t assume you can easily add side panels to your carport or a gate for a barn-style carport, as a lightweight metal frame may not easily support added rivets and screws for these add-ons. It may be best to determine what upgrades you want rather than starting with a simple carport, and choose the right style that has all these upgrades and additions included. And you can read more about custom-designed carports to decide which additions or upgrades are within reach.
