Distribution of soil pressure under a footing is a function of the type of soil, the relative rigidity of the soil and the footing, and the depth of foundation at level of contact between footing and soil. A concrete footing on sand will have a pressure distribution similar to Fig.(a). When a rigid footing is resting on sandy soil, the sand near the edges of the footing tends to displace laterally when the footing is loaded. This tends to decrease in soil pressure near the edges, whereas soil away from the edges of footing is relatively confined

#Stone_Pitching_Basic_Purpose: 1) Erosion of U/S and D/S face: When water flows over these slopes, it exerts a force that can remove soil particles and cause erosion. This erosion weakens the slope, leading to instability and potential failure of the structure. By placing stones or rocks on the slope, the erosive forces of the water are dissipated, protecting the U/S and D/S faces from erosion. 2) Cracking due to frost action: Frost action occurs when water freezes and expands within the pores and cracks of rocks and soil. This expansion can cause cracking and damage to the slope. While stone pitching can provide some protection against frost action by covering the surface and reducing direct exposure to water, it is not the primary purpose of this method. Other measures such as proper drainage and insulation may be required to minimize the effects of frost action. 3) Gully Formation: Gully formation refers to the creation of deep channels or ravines due to the erosive action of water. When water flows over unprotected slopes, it can concentrate its energy on specific areas, leading to the formation of gullies. These gullies can cause further erosion and instability of the slope. Stone pitching or riprap helps to distribute the energy of flowing water, preventing the concentration of erosive forces and minimizing the chances of gully formation.

sediment scour modeling around a group of concrete tetrapods. These structures are vital in safeguarding our coastlines from the relentless forces of waves and currents. However, traditional breakwater foundations can face challenges. Wave action can create issues like suffusion and suction, compromising the structural integrity of the breakwater and leading to expensive repairs. Ridgeway Rockbags® are changing the game in breakwater construction. They offer a robust and stable foundation for armour layers like these tetrapods, significantly mitigating the risks of scour and undermining. By providing a more resilient base, Ridgeway rockbags help ensure the long-term effectiveness and durability of coastal protection structures, saving time, money, and resources in the long run. #CoastalProtection #SedimentScour #Tetrapods #Breakwater #RidgewayRockbags #WaveAction #StructuralIntegrity #SustainableConstruction

Check out this in progress short clip of a very beautiful home. We are currently in the stage of installing piles then I will keep you informed on the progression of this build. Piles are used on homes near the ocean primarily for structural support and stability. The soil near coastal areas is often loose or sandy, which may not provide sufficient support for traditional foundation types. Piles, which are long, slender columns driven deep into the ground, help distribute the weight of the structure more evenly and anchor it securely to stable soil or bedrock below. This helps protect the home from potential damage due to erosion, shifting sands, and the forces of waves and tides commonly experienced in coastal regions. #piledriving #cranes #soilstabilization #foundation #compaction #concreteconstruction #cylinder #heavyequipment #drainage #newconstructionhomes #soiltesting #compactequipment

The topic is termite damage. It's not always easy to see structural damage from termites, but termites often leave trails that point to where they may have damaged wood. Look for termite shelter tubes, follow the trails, and then PROBE the wood to see how much damage there may be. Sometimes the wood looks fine but by using a pick or screwdriver you might plunge it straight through the wood. You can also gently drill areas of suspected wood damage with a 1/8" drill bit and "feel" the soft or damaged areas. #structuralengineer #structuralinspection #termites #termitedamage #advancedst

Where you place your drainage and how deep it is laid will play a big role in the success of keeping your basement dry. In this video Dylan shows you the where and why behind the trenching.
