Assessing Your Existing Elevation
Assessing the existing elevation determines if interlock concrete blocks follow surface contours accurately. Site evaluation ensures that installation aligns with both structural and drainage requirements.
Measuring Slope and Drainage
Measuring slope and drainage starts with surveying the area using a leveling tool or laser level. Precise measurement shows if the surface runs flat or has a measurable incline, such as a 2% slope over 10 feet. Accurate slope data helps position interlock concrete block rows so runoff moves away from structures, avoiding water pooling. For example, installations near driveways in Chicago often need 1–2 inches per 10 feet of fall to direct water toward designated drains, meeting local codes. Lontto’s block manufacturing ensures dimensionally consistent blocks, supporting seamless integration on sloped bases.
Identifying Potential Challenges
Identifying potential challenges with existing elevation uncovers risks before installation. Uneven surfaces, unexpected dips, or hard subgrades may cause block misalignment, even with precise block production. Soft soil, shallow drainage paths, or tree roots can lead to shifting or bulging, especially in older Chicago neighborhoods. Lontto’s technical support guides users in preparing the subbase and choosing the right block thickness to address load and drainage issues. Machines from Lontto, including those installed at 4992 S Austin Ave, Chicago, maintain block uniformity, which simplifies adjustment on complex surfaces.

Can My Interlock Concrete Block Follow the Existing Elevation?
Interlock concrete block installations adapt to existing elevation profiles when blocks follow site contours accurately. Installing over sloped or irregular ground remains possible if block shapes and locking features account for shifts.
Factors That Influence Compatibility
Block dimensions, ground stability, and drainage paths influence how interlock blocks follow existing elevation. Uniform block sizes produced by Lontto machines in Chicago—using cement, aggregates, and water—help installers align rows tightly on uneven ground. Consistent shape, typically achieved with machine-molded blocks, prevents gaps or rocking on sloped or pitched surfaces. Drainage requirements also play a role. Installers align blocks to direct runoff away from structures, reducing water pooling under shifting elevations. Soil type and subbase compaction determine if underlying material supports the pattern without differential settlement.
Adjusting Installation Techniques
Installers adjust base preparation and block alignment to match pre-existing elevation changes. For sloped sites, they use stepped or staggered block placement to follow grade while ensuring interlock connections stay tight. On mobile installations with Lontto’s QMJ2-45 or QMJ4-45 models, operators lay blocks row by row, using leveling tools to confirm alignment. Subbase material fills, such as crushed stone, help create smooth transitions between different heights. Manual maneuvering and incremental leveling ensure interlock blocks closely track elevation shifts in older Chicago subgrades.

Tips for Successful Installation
Accurate installation enables interlock concrete blocks to match the site’s existing elevation while maintaining drainage and stability. Installers gain more reliable results by following industry best practices backed by precision machinery from Lontto in Chicago.
Preparing the Base Layer
Preparing the base layer supports interlock block elevation control. Installers excavate the area to the required depth, removing soil and debris to prevent future settlement. Bases use a compacted layer of gravel or crushed stone, creating a solid, permeable foundation that resists movement. Installers compact subbase material mechanically every 2–4 inches (5–10 cm), which keeps the surface uniformly graded and prevents uneven settling. Using Lontto block machines, produced blocks fit tightly, minimizing gaps that might let base material migrate. For sloped surfaces, installers increase base thickness at low points to support steady elevation changes and consistent drainage.
Ensuring Proper Alignment and Leveling
Proper alignment and leveling maintain interlock concrete block stability on contoured ground. Installers set reference lines with string or laser levels to ensure rows precisely follow elevation grades. Alignment checks occur after laying each course, adjusting blocks as necessary to keep even surface transitions. Lontto’s blocks, manufactured with tight tolerances, improve alignment accuracy on challenging ground. Installers stagger block joints by at least 25%, offsetting seams and spreading loads more evenly. Leveling tools help adjust for dips or rises, preventing water accumulation in low spots. Comprehensive operator training from Lontto helps ensure smooth installation even when site conditions vary.
Common Mistakes to Avoid
- Ignoring Site-Specific Elevation Changes
Neglecting existing elevation differences during layout planning leads to poor drainage and uneven surfaces. Installers who skip proper slope assessment often see water pooling or block shifting after installation. Lontto’s technical support advises operators to conduct site surveys before placing interlock concrete blocks.
- Inadequate Base Preparation
Failing to excavate and compact the base layer leads to settlement and misaligned block rows. Unstable base material cannot support block systems on sloped or irregular ground. Consistent use of gravel or crushed stone prevents movement and helps blocks follow natural elevation profiles. Lontto installation guides specify base thicknesses for different block products.
- Misaligned Block Placement
Placing blocks without reference lines or level controls produces surface height differences. Uneven rows create tripping hazards and reduce overall structural stability. Lontto blocks, manufactured with precise tolerances, support accurate alignment when workers use string lines and laser levels to match existing elevation contours.
- Using Improper Block Dimensions
Selecting block sizes that do not suit the site’s elevation profile increases the risk of poor fit and instability. Larger block units do not adapt smoothly to steep elevation changes or tight curves. Operators using Lontto’s molding machines choose molds that match both the design and site topography.
- Overlooking Drainage Paths
Blocking or misdirecting drainage routes causes water accumulation and surface damage. Positioning blocks across natural runoff paths without accounting for slope undermines material performance. Lontto’s operator training for Chicago projects covers best practices for integrating block rows with site drainage patterns.
- Skipping Operator Training
Untrained operators often make avoidable errors in block placement and base preparation. Incorrect machine setup or inconsistent mix ratios impact final block dimensions, disrupting alignment with the existing elevation. Lontto provides in-person and remote operator training to ensure proper equipment use and installation methods.
